Changing values in a INI file

I have an application (Toad) that I have virtualized. There is a toad.ini file. In that file there are paths pointing to C:\Documents and Settings\_user1_\Appl...............

When that file is copied to the sandbox it retains the path pointing to C:\Documents and Settings\_user1_\Appl...............

I need it to change that path to each users APPDATA path.

How can I do that?

I hope my explenation is clear?

Thanks
